I'd sell it tomorrow and make about $1bn in profit and move on with my life.
EDIT: I'm editing this because people are missing the point. My point wasn't about how when 1 owner has absolute control BTC is worthless like this guy[1] seems to think or about the liquidity of BTC, like this guy[2] seems to think. My point was about the fact that the difference between BTC is that the only use it has is holding and hoping it moves up, whereas owning a company actually brings in earnings.
